Ferrovanadium Sample Verification

Ferrovanadium Services

Ferrovanadium (FeV), an alloy used as a strengthening additive in the production of certain steel.  The production of ferrovanadium, containing 35–80 percent vanadium, is carried out in an electric-arc furnace. Scrap iron is first melted, and a mixture of V2O5, aluminum, and a flux such as calcium fluoride or calcium oxide is added. In the ensuing reaction, the aluminum metal is converted to alumina, forming a slag, and the V2O5 is reduced to vanadium metal, which is dissolved in the molten iron. Since this oxidation-reduction reaction is exothermic, the heat supply need only develop the kindling temperature of 950° C (1,750° F). After kindling, the electrodes are withdrawn until the reaction is completed; they are then reinserted into the molten slag and the furnace reheated to improve settling.

For a complete listing of ferrovanadium specifications, see ASTM A102.

McCreath Laboratories will send trained, experienced technicians to take a represented sample for you.  Whether in bulk or containers, our technicians have the training, tools and experience to collect a representative sample, ensuring that all subsequent laboratory testing is accurate and reliable.  With our mobile crushing units, ferrovanadium in lump form can be partially processed on site per the ISO and ASTM standards, increasing efficiency and reducing the amount of material taken off-site.

Foundry Experts at McCreath Labs

McCreath Laboratories will employ both classical and advanced in-house techniques in the analysis of ferrovanadium.  The techniques have been verified through the use of certified reference materials and some are adopted directly from ASTM or ISO standards.  A typical ferrochrome analysis would be done as follows:
